The answer for your equation is: y = 9
Answer:
D
Step-by-step explanation:
The angle CDG equals 90 degrees and the angle GDE also equals 90 degrees. Supplementary angles are angles that add up to be 180 degrees.
CDG + GDE = 180 degrees
First, we can note that the relation between the independent and the dependent variables is a linear relation.
We will need two points: (1,3) and (2,5)
The general form of the equation of the linear line is:
y = mx + c where m is the slope and c is the y-intercept
To get the slope, we will use the following rule:
m = (y2-y1) / (x2-x1)
m = (5-3) / (2-1) = 2
The equation of the line now becomes:
y = 2x + c
To get the value of the c, use any of the given points and substitute in the equation. I will use (1,3) as follows:
y = 2x + c
3 = 2(1) + c
c = 3-2 = 1
Therefore, the equation of the line is:
y = 2x + 1
I hope it’s helps i have to write more so I’m writing
Answer:
Approximately Normal, with a mean of 950 and a standard error of 158.11
Step-by-step explanation:
To solve this question, we need to understand the Central Limit Theorem.
The Central Limit Theorem estabilishes that, for a random variable X, with mean 
and standard deviation 
, a large sample size can be approximated to a normal distribution with mean and standard deviation, which is also called standard error 
.
In this problem, we have that:
The sampling distribution of the sample mean amount of money in a savings account is
By the Central Limit Theorem, approximately normal with mean 
and standard error 
So the correct answer is:
Approximately Normal, with a mean of 950 and a standard error of 158.11
